Overhaul
Servicing the front suspension-steering assembly,
described below, deals mainly with replacing parts
(pin- NADELLA roller bushings - sealing rings unit
and dust guard) which connect the steering tube
to the front wheel holder swinging hub.
N.B.
BEFORE PROCEEDING WITH THE DESCRIBED SERVICE,
CHECK THAT THE STEERING TUBE AND THE WHEEL
HOLDER HUB ARE IN EXCELLENT CONDITIONS: ONLY
THEN IS THE SERVICE JUSTIFIABLE.
MOREOVER, REMEMBER THE STEERING TUBE SHOULD
BE REPLACED WITH A NEW ONE WHEN DEFORMED.
a = Ø 12 Punch
b = Sharp-edged end
Use a suitable punch with the dimensions indica-
ted on the figure; hit with a mallet until the wedging
washer is crushed and then extract it with the help
of a pointed end.
Repeat the operation for the second washer using
the punch on the side opposite to the one shown
in the figure.
Use the tool fitted with part 1 as shown in the figure
and move the tool handgrip until the pin and the
NADELLA are simultaneously ejected in the direc-
tion opposite the tool thrusting force.
After removing the pin and the first NADELLA, the
swinging hub gets detached from the steering
tube.
